Which term best describes a deep cut with irregular edges?

• A. Laceration
• B. Contusion
• C. Abrasion
• D. Puncture

Answer: (A)

When distinguishing wound types, focus on how the skin is breached and what the edges look like. A laceration refers to a deep cut where tissue is torn, producing irregular, jagged edges rather than clean, smooth margins. This tearing often results from blunt trauma or a crushing/shearing force, which explains the uneven edges and potential depth.

In contrast, a contusion is a bruise with no break in the skin, just underlying tissue damage. An abrasion is a superficial scrape that wears away the outer skin layer. A puncture is a small entry wound caused by a pointed object, typically narrow and deep but with a clean or defined edge rather than torn tissue.
